The rear rig' l2 may have rigidly connected thereto a vertically extending arm structure 25 through which power may be derived for the purpose of pivoting the rig about its pivot '23. V 1 Carried by the supportingmeans l5 and thus indirectly connected to thetractor'is a lever adapted ior pivqtal movement abdut'j its pivot:

Be- H tween these two levers is connected 2. rod member 30, for pivotal movement with respect thereto, I

at the free ends of the same; it should now' be seen that there has been provided a' movable 42 provides for deeper working depthof the rigs H and I2. I

As a means for rnaintaining the movable means against the adjustable stopmeehanism with the rigs in their'working position, there is provided a spring 43 connectedobetween the lever 4| andthe rod member 3|l of the movable means. 13' vvill maiiitalnfthel same against the adjustable stop and at-"the 'san etime tend to hold therigs in their ground-working positions. 1

The movable oer-rung means is adapted tobe Tpre ssurethrough a'fiexible'ccnnection 45 from a device located withinthe shell of the tractor'and' adapted to be driven by the trac- T t-or mechanism. Such a hydilallli0 arrangement means which extends substantially the entire I length of the tractor and adapted tohavemotion, generally in a vertical plane and in a fare and aft direction. This movable means comprises, in general, two pivoted levers one atone locai shown in the pending-application to A; C. Lindgrenoet al., Serial No. 181,778; filed December 27,

193?}no'w Patent No. 2,213,401, dated Sept. 3,

1940., While a hydraulic arrangement has been it should-be evident that any particular tion on'the tractonrand a'second' at another location on -the tractor and the ;free ends or the same being interconnectedbv-a .rod member.

This rod member provides meanslocatedalong the extent of the tractor from which the'various independently connected implements rnayreceive lifting power regardless oi theirposition along the tractor. To this same lifting means m aybe connected the rig located on the forward pcrtion of'the tractor or there maybe connected the rig I; located on'the rear of the tractor, V

The r-ig ll is'connected by meanspf a 3| tethered 30 in armanner wellknown in the end which will" engage a. plateilearried by the rod 30jupon its lever moving in a'forward-direction.;;As the collar .32 engagesthe plateiilfthe 4o rig H is. pivotedaboutits' conne tion witlythe transverse supporting-member liandmoved vertica ly to a transport position;

V The ,rig l2 may gbe similarlyconnected to the forrn of'rpower means known to the-art could be readily adapted ta -operate the movable means.

Serving as .a support forthemovable portion of the cylinder device is a swinga-ble supper-ting lever -4 5 connected -forpivotail movement to the tractor at 41. The-cylinder device 44 is anchored mul bracket structure at 48. The connection 'with the rnovable part of thefdev-ice 44 to the movable means ins-made through a link -49 to the second' lever 28Jenthe'rearof-the tractor. This Y Qylindergdevice ldisprelerably of the singleactingtyrieand serves tomove the entire mov able means, ;in the forward direction thereby to efiect lifting oijtherespective rigsl'l and Q. It,

should now be apparent from th'eabove description that therehasv been provided on the tractor rod member 30 at the rearwardlocation by means 01 a lift rod 34 having aeoll-ar 35v adapted teen gage with the arm structure 25 as the lift rod 34 may be connected directly to the rod member 30 or-it may beconnected byuneahs of a plug .34 is pulled forward' by "the rodmember 30 that. forms apart of thelifti-ng means. This lift rod member 3i d-isposedein the rear endefgthe rod 3-0, which ispreferably 'in t-he form of a pipe.

, "This ;plug jcangb'e maintained within the end of the ,rod '3! by a bolt 31 to form a connection-for an eye'portion 38 of the :rod 34; the plug adhe ing. folded to provide 'a laterally extending portion which portionaiso serves as apointwith which the adjustable stop 'rn'echam'srndfl 'gmay engage Thisadjustablestop mechanism.
